3.5, y2-y1 / x2-x1 or rise/run
Answer:
The average speed of the plain was 800 miles/h.
Step-by-step explanation:
To solve this problem we first need to convert the time the tain took to finish the journey to hours. To do that we will divide the part that is in minutes by 60 and sum to the part that is in hours, we have:
time = 3 + 33/60 = 3 + 0.55 = 3.55 hours
The average speed is given by the following formula:
average speed = distance/time
average speed = 2840/3.55 = 800 miles/h
The average speed of the plain was 800 miles/h.
Answer:
The values of k are 2/3 and -1
Step-by-step explanation:
Product of zeros = αβ= constant / coefficient of x^2 = 4/k
Sum of zeros =α+β = - coefficient of x / coefficient of x^2= -4/k
Given
Consider a= α and b= β
can be written as 
if we add 
in the above equation.
Putting values of αβ and α+β
The values of k are 2/3 and -1
Answer:
y=2/3x+1
Step-by-step explanation:
y int= 1,
using rise/run for slope, 2/3=m
Answer:
Step-by-step explanation:
Since both equations have 
, we can subtract the second equation from the first to try and solve for 
:
With this, we can plug the value back into the first equation to solve for 
:
Therefore, the solution is
